We show that the Gersten derivation of Maxwell equations can be generalized. It actually leads to additional solutions of ?S=1 equations.?

It is proved that necessary corrections in the Evans-Viger modified electrodynamics invalidate the arguments given by E. Comay [CPL 261 (1996) 601] against this model. From the conceptual viewpoint the Evans/Comay discussions in several journals have created much confusion.

Quantum electrodynamics is a well-accepted theory. But, we believe it useful to look at formalisms which provide alternative ways to describe light, because the development of quantum field theories based primarily on the gauge principle have, in recent years, met with considerable difficulties. There are numerous generalized theories and, mainly, they are characterized by introducing some additional parameters and/or longitudinal modes of electromagnetism. The Majorana?Oppenheimer form of electrodynamics, the Sachs'' theory of Elementary Matter, the analysis of the action-at-a-distance concept, presented recently by Chubykalo and Smirnov-Rueda, and the analysis of the claimed longitudinality of the anti?symmetric tensor field after quantization are examined in this article. We list also recent advances in the Weinberg 2(2J+1) formalism (which is built on first principles) and in the Majorana theory for neutral particles. They can serve as starting points for constructing the quantum theory of light.

Quantum electrodynamics is the well-accepted theory. However, we feel it is useful to look at formalisms that provide alternative ways to describe light, because in the recent years the development of quantum field theories based primarily on the gauge principle has encountered considerable difficulties. There is a wide variety of generalized theories, and they are characterized mainly by the introduction of additional parameters and/or longitudinal modes of electromagnetism. The Majorana-Oppenheimer form of electrodynamics, the Sachs theory of Elementary Matter, the analysis of the action-at-a-distance concept, presented recently by Chubykalo and Smirnov-Rueda, and the analysis of the claimed "longitudinality" of the antisymmetric tensor field after quantization are reviewed in this essay. We also list recent advances in the Weinberg 2 (2J+1)(2J+1) formalism (which is built on First Principles) and in the Majorana theory of neutral particles. These may serve as starting points for constructing a quantum theory of light.

In this small note we ask several questions which are relevant to the construction of the self-consistent neutrino theory of light. The previous confusions in such attempts are explained in the more detailed publication.

On the basis of ordinary mathematical methods we discuss new classes of solutions of the Maxwell's equations discovered in papers by D. Ahluwalia, M. Evans and H. Munera et al.
